How to Prepare Physics for UPSC Exam? – Important Topics

Physics for UPSC Exams: Here we are providing important topics in Physics for UPSC Exam. You will find Tips on how to crack Physics in upsc ias exam. It is adviced to take Physics as optional subjects if you are from engineering background because course is almost similar and all concepts we have you have already studied. Below you will find all important topics in Physics for UPSC Exam so that you can prepare wisely. Find out strategy to prepare Physics for IAS Exams. Here are few essential topics in physics that are helpful to score the maximum marks is the less time. You should also prepare other remaining topics once you are done with these important topics to geet good score in Physics.

Important Topics in Physics for UPSC Exams

Paper I

Section A has 3 crucial areas: Classical Mechanics, Special Relativity, Waves and Geometrical Optics and Physical Optics. As all these three sections provides mandatory questions, it’s suggested not to ignore any one of that. Yet, if you are hard pressed for time, you can be selective about any one section. But it’s crucial that before getting selective you have noticed the necessary areas depending upon the past trend analysis.

It’s advisable not to be selective in case of Classical Mechanics. Also, there is no dearth of good study material regarding this section. Most of the students find this section rather easy in solving questions. In Special Relativity, the older topics are more crucial than the newly added ones. So, the students should design the preparation strategy accordingly. As far as the Waves section is concerned, Damped and Forced Vibrations, Phase and Group Velocity should be given more preference.

Section B consists: Electricity and Magnetism, EM Theory and Black Body radiation and Thermal and Statistical Physics. All the above mentioned three sections carry some mandatory questions, hence none of them can be wholly ignored. Questions which come on EM Theory are very easy and very scoring. Hence, this should be thoroughly prepared and the students must not miss even a small portion on this area.

Paper II

The entire second paper except Electronics can be well prepared from two supreme sources, i.e.. Quantum Physics by Resnick and Eisberg, and Modern Physics by Arthur Beiser. For value addition, you may require to put some extra efforts in reading from some other standard books.


Electronics is a very core content in the course. Students who belong to non-electronics background must have to make the extra efforts and work more harder to get command over this section thoroughly. Once when you are done with it, this part can proves very much scoring to you.
